Zone Plate design

I've read a number of papers explaining the physics of a Zone Plate.
However, I haven't seen anything that deals with the number of Zones that
comprise the Zone Plate.

Is there an optimum number of zones? Does it change with the focal length?
What is the effect on resolution & depth of field?

Thanks,
